Just install a jacksonracing m45 yesterday. 2 problems appear after I started the car. There was a loud screech if the RPM hits 2.5k+ and if you press the gas pedal the RPM will jump from .5 to 2k RPM and sometime kills the engine if it drops to 0. I fixed the loud screech which turns out to be a lose belt. So the screech is gone but now stuck with the RPM jumping. The car ran fine before installing the supercharger. I think theirs a leak somewhere where the silicon hose is not tight but not sure. Any advice is welcome.

Edit: Fixed my own problem. Was leaking air.
